Classing Guidelines

You are here: Home / Classing Guidelines

It is difficult to give advice about classing particular clips without viewing the Mohair. The following should be regarding as a guideline only.

Classing is the grading of Mohair according fineness, length and type. Uniformity of all the Mohair within one line has an important bearing upon its value.
The classer’s aim should always be to accumulate large even lines, but pigmented, kempy, stained or short Mohair must be kept separate from the main lines.

The classer should consider the following:

The possible lines for lustrous Mohair are:

Superfine Kid Fleece              SFK  26 microns

Fine Kid Fleece                       FK  30 microns

Young Goat Mohair                 YG  32 microns

Adult Hair                                 H    34 microns

Strong Adult Hair                    SH   36 microns

 

Evenness of length is extremely important when marketing Mohair. The ideal length being between 90mm and 150mm.
In large lots of Mohair it may be possible to grade the hair into separate lengths, i.e. 150mm, 125mm, 90mm.
However in most cases 90mm to 150mm, hair will need to be blended. It is suggested therefore that three lengths be made:

A          90mm-150mm

B          Under 90mm

Thus a long lustrous fleece of 25 microns would be classified as AFK, a short lustrous fleece of 32 microns would be classified as BH,
and excessively long hair should be kept separate.

Evaluations of sale lots over ten years in South Africa have shown that whilst style and character does not affect price to the same extent that fineness does,
it nevertheless is significant. Therefore fleeces lacking style and character should not be included in the top fleece lines.

After the fleece has been skirted and the stained and kempty portions removed, the fleece should be carefully appraised
as outlines for Fineness, Length, Style and Character.

The fleece may have to be subdivided into tow or more lines. Usually the longest and coarsest mohair occurs on the neck –
the britch may often be shorter and contain more kemp whilst the shoulders and flank form the average. Well bred goats should have even fibre throughout.

Classing from the table into plastic containers and then checking the contents into bins is a useful practice that is often adopted.

Most Angora flocks are relatively small, so that most classed lines will not be sufficient to make individual bale lots. Therefore mixed or bar bales are pressed.

 Note: Do not press wet mohair – stains must be dried before pressing.

A Specification sheet detailing the clip should be completed and forwarded to the selling agent.

It is interesting to note that in South Africa the classing of mohair is governed by Government Notice which requires that certain parts of the fleece such as “breech hair, wasty backs, urine stained hair, locks, shall be packed separately”.
